Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need in distributed systems to determine the source of performance or service degradation that interferes with satisfying required Service Level Agreements (SLA) or Quality of Service (QoS), particularly in networks handling multimedia transmissions where issues like packet dropouts and frame freezing occur.
Innovation Solution
A method and device that model the distributed system, identify associated network components, monitor performance criteria, and determine the source of degradation by analyzing routes and components within the network, using a processor to execute these steps and provide instructions for a computer system to execute the method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network bandwidth is increased to guarantee flawless multimedia presentation, then service quality is improved, but network cost and complexity increase
Solution Approach 1:
The patent applies preliminary action by proactively monitoring performance criteria and identifying degradation sources before they cause actual service failures. The system continuously tracks network elements and performance metrics, enabling early detection and intervention to prevent packet dropouts and frame freezing, thereby maintaining service quality without requiring excessive network bandwidth
Solution Approach 2:
The patent implements feedback mechanisms by monitoring performance criteria and using this information to dynamically adjust network routing and resource allocation. The system collects performance data from network elements, analyzes degradation patterns, and adjusts traffic routing in real-time to maintain service quality while optimizing network resource usage
2Difficulty of detecting and measuring
If network monitoring and analysis capabilities are enhanced to identify performance degradation sources, then troubleshooting efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the network into discrete monitored elements and breaking down performance degradation analysis into specific measurable criteria. The system segments network monitoring into individual element performance tracking and aggregates this data to identify degradation sources, making the complex task of troubleshooting manageable through structured analysis of component-level metrics
Solution Approach 2:
The patent introduces an intermediary analysis layer that sits between raw network performance data and troubleshooting decisions. This intermediary system processes performance criteria data, correlates it with network element status, and presents synthesized degradation source identification, simplifying the complexity of analyzing raw network data while improving detection capability
